63 Dodge Dart newcomer questions/advice

I've got a driveshaft with ball and trunnion setup from a '64 Dart - slant 6, 3 spd manual A903 - per this post, Slant Six Dan (Post #4) says it's the same length for manual or auto
If you want it, it's yours for cost of shipping (and, anybody got recommendations on how to ship a driveshaft?)

A member shipped on to me thru UPS a couple of years ago. Its for a Valiant, though so it's between 3 and 4 inches shorter than the one you need.
